Description

Reinforced conductive connector

The present invention relates to a reinforced conductive connector, in particular, the spring steel sheet and the busbar have reinforced structures corresponding to each other.

Common electrical wire connectors are mainly used to connect power distribution boards or the like, or to connect the ends of electrical wires between electrical items or accessories and the power supply, and can form one or more circuit loops, indeed Steady achieve the purpose of one-to-one, one-to-many or many-to-many electrical connection, and can be divided into two types: temporary connection or permanent connection, usually portable micro connectors are used for temporary connection and can be disassembled.
